The DFT's are noted in table area. The minimum required by specification is 10.0 mils. The low areas found will be recoated today along with a brush touch up to pin holes in welds. Most of the low areas were found on outer ceiling plate and wall / ceiling brace pieces. Some of the roof beams were also a little low. Small holidays of primer showed on bottoms of some roof beams. Overall the ceiling looked pretty good and today's touch up coating should complete the ceiling area.
